months of tension between the Vipers factions the storyline was suddenly dropped and the feuding factions reunited, dropping Pentagón, Shiiba and El Cuervo from the group but adding Tokyo Viper to the group. Los Vipers regained the Atómicos title on April 15, 2000 effectively ending the storyline with Los Vatos Locos for the time being. With the internal struggles in Los Vipers settled Abismo Negro and Electroshock focused on regaining the tag team titles, which they accomplished on May 7, 2000 by defeating Hator and the Panther. The team only held onto the title for 63 days before losing the belts to the duo of Perro Aguayo, Jr. and Héctor Garza. Not longer after Los Vipers reunited, Cibernético formed a new group called Lucha Libre Latina (LLL), a group intent on taking over AAA that was inspired by World Championship Wrestling's New World Order. Los Vipers became a subgroup within LLL, and Abismo Negro assumed leadership of Los Vipers after Cibernético. Los Vipers reigned as Atómicos champions for over a year, until they were surprisingly upset by a little known group called Los Regio Guapos (Hator, Monje Negro, Jr., Potro, Jr. and Tigre Universitario) on August 19, 2001. Los Regio Guapos only held the title for under two months before Los Vipers regained the title and began their fourth reign with the Atómicos title. Their fourth reign also turned out to be the last reign for Los Vipers, ending on November 23, 2001 as a new version of Los Vatos Locos (Espiritu, Nygma, Picudo and Silver Cat) defeated them in one of the featured matches of the 2001 Guerra de Titanes. As time passed the size of Los Vipers diminished until it was mainly Maniaco, Histeria, Psicosis II and Mosco de la Merced representing the group. Los Vipers took part in an eight-man Steel cage match at Triplemanía X against Los Diabolicos (Mr. Condor, Ángel Mortal and El Gallego) and Gran Apache where the last wrestler in the cage would lose either his mask or be shaved bald. Maniaco ended up as the last man in the ring and was forced to unmask. Following Maniaco's mask loss he departed AAA. Over the summer of 2004 Los Vipers, in this case Mosco, Histeria and Psicosis II became involved in a feud with Heavy Metal, El Intocable and Zorro that led to a Steel Cage match at Verano de Escandalo 2004 in
